Memento Mori

With ex-Candlemass
frontman Messiah Marcolin supplying the vocals, one would expect
Memento Mori to have at least a passing resemblance to Candlemass,
and sure enough they do, though in general Mememto Mori is somewhat
more power metal and less doom.
Also not surprisingly, the one non-Messiah album,
La Danse Macabre, is the least doomy of their albums.
As shown below, the band had many ties to other Swedish power/doom
metal bands of the day.
